In our recent project, we designed a gear tank for a tug-of-war competition, focusing on maximizing torque through a strategic gear system. By using a pre-built AGV tank from the Sophomores, we saved time and concentrated on optimizing our gear design. Our unique vertical gear arrangement distinguished us from other teams, which primarily used horizontal systems. Throughout the building process, we faced challenges with gear meshing, prompting us to experiment with various gear ratios. Ultimately, we implemented two different gear ratios on either side of the tank, enhancing performance. After 640 minutes of teamwork and problem-solving, we successfully tied for first place, achieving a torque of approximately 20N.
In our recent experiment, we aimed to create a closed-loop robotic system using various motion-converting mechanisms. Our group modified a previous robot from the "Silly Walks" project, which utilized rotary to linear motion without circular wheels. We enhanced this robot by adding an extra motor and 24-tooth gears to represent rack and pinion linear motion. Over 10 class periods, totaling 800 minutes, we developed a robot capable of pressing a button on another robot in the system, allowing it to participate in the closed-loop operation. Once activated, our robot would move 36 inches to touch the other robot's button and then return to complete the cycle. While our robot functioned efficiently within the system, the overall closed-loop system was not fully realized due to one group's robot not operating correctly.
